Motorola IMPRES 4200MAH Li-IonHigh-Capacity Rugged (IP68) Battery

IMPRES batteries when used with an IMPRES charger provide automatic, adaptive reconditioning, end-of-life display, and other advanced features. Data is stored in the battery and communicated to the charger via a unique IMPRES communication protocol which is designed to maximize talk-time and optimize battery cycle life — all automatically. This rugged battery meets an even more stringent military standard (MIL-STD-810E, Method 512.3 Immersion) allowing it to be submerged in water for up to 2 hours.
